Abstract

A wearable body composition analyzer according to various embodiments of the present disclosure may include an induction part for inducing secretion of bodily liquid while being in contact with a body part, a collection part that collects the bodily liquid secreted, a sensor part that detects a body composition from the bodily liquid collected, and a wearable part to which the induction part and the collection part is detachably attached, wherein the wearable part may be worn on a body. The above-described wearable body composition analyzer may be implemented variously according to embodiments.

Claims

1. A wearable body composition analyzer comprising:

an induction circuit configured to induce a secretion of a bodily liquid from a body part;

a collector configured to collect the bodily liquid secreted;

a sensor configured to detect a body composition from the bodily liquid collected by the collector; and

a wearable part configured to detachably receive each of the induction circuit, the collector, and the sensor, so that the induction circuit, the collector, and the sensor are slidingly received in a groove in the wearable part so as to be removable when desired,

wherein the wearable part is configured to be worn on the body;

wherein the analyzer further comprises a driving circuit and an induction body part providing a support groove, wherein the driving circuit comprises a protrusion part, and wherein the protrusion part is configured to connect the driving circuit with the induction body part when the protrusion part is inserted into the support groove of the induction body part.

2. The wearable body composition analyzer of claim 1, wherein the collector comprises:

a space provision part that provides a collection space in which the bodily liquid secreted is collected while the space provision part is in contact with the body part; and

a movement path part communicating with the collection space, through which the bodily liquid is moved.

3. The wearable body composition analyzer of claim 2, wherein the space provision part comprises:

a cover part that has a communication opening formed therein to communicate with the movement path part;

a contact part that extends from a lower portion of the cover part to be in contact with the body part, and constitutes a closed curve to form the collection space; and

a support part that extends from the lower portion of the cover part within the closed curve constituting the contact part, wherein the support part prevents a close contact between the cover part and the body part.

4. The wearable body composition analyzer of claim 2, wherein the movement path part comprises a sensor coupling part to couple to the sensor.

5. The wearable body composition analyzer of claim 2, wherein the movement path part is made of a hydrophilic material and one end of the movement path part is made of a hydrophobic material.

6. The wearable body composition analyzer of claim 1, wherein the sensor is configured to detect glucose from the bodily liquid.

7. The wearable body composition analyzer of claim 1, wherein the induction circuit comprises a driving circuit that also provides a signal to the sensor.

8. The wearable body composition analyzer of claim 7, wherein the driving circuit comprises:

a first connection circuit connected to the induction circuit; and

a second connection circuit connected to the sensor.

9. The wearable body composition analyzer of claim 7, wherein the induction circuit comprises an inductive agent that induces the secretion of the bodily liquid, wherein the inductive agent is injected into the body part by the signal applied from the driving circuit.

10. The wearable body composition analyzer of claim 7, wherein the sensor comprises:

an operation electrode operated by the signal applied from the driving circuit; and

a counter electrode arranged to be spaced apart from the operation electrode,

wherein the sensor is configured to detect a current by a body composition between the operation electrode and the counter electrode.

11. The wearable body composition analyzer of claim 10, wherein the sensor comprises an auxiliary electrode arranged to be spaced apart from the operation electrode, and the auxiliary electrode is configured to determine whether there is bodily liquid by detecting the current flowing between the operation electrode and the auxiliary electrode.

12. The wearable body composition analyzer of claim 7, further comprising a plurality of attachment parts detachably attached to the wearable part, to which the sensor part and the induction circuit are attached, wherein the plurality of attachment parts are arranged in a circumference of the driving circuit part along a circumferential direction of the wearable part.

13. The wearable body composition analyzer of claim 12, wherein the induction circuit comprises:

a first induction part which protrudes from one surface of the attachment part and is arranged to be spaced apart from the circumference of the sensor; and

a second induction part which protrudes from one surface of the attachment part and is arranged between the first induction part and the sensor part.

14. The wearable body composition analyzer of claim 12, further comprising a washing part mounted to the wearable part to spray washing liquid at a part where the attachment part is in contact with the body part.
